From d0464bcf12af54bafe02dd23ac5bd75d825f9fdd Mon Sep 17 00:00:00 2001 From: John Youn Date: Fri, 13 Nov 2015 17:02:10 +0000 Subject: [PATCH] usb: dwc2: Make PHY optional Fixes commit 09a75e857790 ("usb: dwc2: refactor common low-level hw code to platform.c") The above commit consolidated the low-level phy access into a common location. This change introduced a check from the gadget requiring that a PHY is specified. This requirement never existed on the host side and broke some platforms when it was moved into platform.c. The gadget doesn't require the PHY either so remove the check.
